Abstract (en)

A water-soluble composition including a water soluble polyamine adduct which is a reaction product of: (a) an alkoxy group modified polyepoxide resin containing an average of at least 1.5 epoxide groups per molecule; and (b) a Mannich base polyamine. The Mannich base polyamine is a reaction product of a polyamine containing at least two amino groups with a N-Mannich condensate prepared from a reaction of a phenolic compound, an aldehyde, and a secondary amine wherein the secondary amine of the N-Mannich condensate is replaced by one of the at least two amino groups of the polyamine, and wherein the ratio of the Mannich base polyamine to the alkoxy group modified polyepoxide resin contains an excess of an active amine hydrogen relative to epoxide groups so that the water soluble polyamine adduct has an amine hydrogen equivalent weight of at most 1000 based on solids content.
